Title: Emergency supply system for a hydraulic circuit
IPC: F15B20/00
Filed: 1970-08-24
Abstract: 1314375 Vehicle hydraulic circuits CATERPILLAR TRACTOR CO 24 Aug 1970 [4 Sept 1969] 40667/70 Heading B7H In an hydraulic supply system for, e.g. a vehicle steering mechanism, an engine driven pump 10 normally providing fluid under pressure is supplemented by a wheel or ground driven pump 40 when the flow rate from the engine driven pump 10 falls below a predetermined value. In a preferred embodiment, Fig. 2, flow from the engine driven pump 10 enters flow control and sensing unit 18 from tank 12 and flows via a Venturi nozzle 76 and check valve 50 outwardly through line 20 to the steering system. Flow from the wheel driven pump 40 enters through line 44 or 46 depending upon direction of vehicle travel and influences spool 52 to the right or to the left thus uncovering a centrally disposed passage 66. Fluid is admitted depending on pump 10 flow rate either back to tank 12 via check valve 68 or to combine with or replace flow from engine pump 10 via check valve 70. This is accomplished since pressure in the Venturi 76 is sensed through a passage 78 at the upstream portion and through passage 80 at the downstream portion. Thus a greater pressure is applied to the top of a spool valve 74 by passage 78 thus connecting the spring chamber of valve 68 through passages 82, 84 with exhaust line 48, so the valve 68 remains open and the pump 40 is ineffectual. Upon reduction of flow in line 16 pressure in passage 78 is reduced and pressure in passage 80 combined with the force of spring 86 moves spool 74 upwardly so that valve 68 will remain closed due to pressure applied via passage 72. Flow from pump 40 will open check valve 70 and supplement or replace flow from the engine driven pump 40. In a modification, Fig. 3, spool 90 is urged to the right against the action of a spring when there is relatively low pressure in passage 78<SP>1</SP> and flow from the wheel driven pump opens valve 70<SP>1</SP> to supplement or replace the flow from the engine driven pump.

Title: A warning and/or control device for use with aircraft fuel supply systems
Inventor: YOUNG JOHN MICHAEL CRISPIN
IPC: H01H35/24
Filed: 1959-12-01
Abstract: 892,951. Device responsive of cavitation in fuel pump systems. LUCAS (INDUSTRIES) Ltd., JOSEPH. Nov. 25, 1960 [Dec. 1, 1959], No. 40729/59. Class 69 (1).  A device has a member which moves between an operative and an inoperative position to give warning and/or to effect control if the pressure of fuel on the upstream side of the pump of an aircraft engine fuel-supply system falls to a value approaching that at which the fuel will cavitate ; the movement of the member being responsive both to the pressure of fuel at the upstream side of the pump and to the vapour pressure of the fuel. Fig. 1 shows an embodiment in which chambers 7 and 6, separated by a flexible diaphragm 8, are connected respectively to the fuel conduit at x, which is adjacent the pump inlet (not shown), and at y, which is upstream of x. A closed, flexible bellows 10 in the chamber 6 is subjected internally to suction from a chamber 13 wherein fuel from the downstream side of the pump ejects from a Venturi nozzle 14 into an outlet 15 in the fuel conduit intermediate of points x and y. A rod extends from the bellows to the diaphragm 8 in such manner that the appropriate pressure differences in the chambers 6, 7 and 13 can cause an extension of the rod to move against the action of a spring 9 in the chamber 7 to close the switch 11 of a warning lamp 12. The required boost pressure, P, is given approximately by the expression P=aF<SP>2</SP>+bPv+c. Where F is the fuel flow, Pv the fuel vapour pressure and a, b and c are constants. F<SP>2</SP> varies as the pressure difference between the points x and y so that the conditions in the chambers 6, 7 and 13 correspond to those affecting the operation of the pump. In an alternative construction (Fig. 2, not shown), the bellows are omitted and the chamber 13 connects direct with the chamber 6 which is unconnected with point y, thereby being subjected solely to the vapour pressure whose normal difference from the boost pressure is balanced by the spring 9 now housed in the chamber 6. In an embodiment illustrated in Fig. 4, in addition to operating the lamp 12 the device also operates, by way of a conduit 31, a servo mechanism (not shown) which controls the boost pressure. Two diaphragms 25 and 26 separate three chambers 22, 23 and 24 which are each appropriately connected to the main fuel conduit. The compensating spring is situated in the vapour-chamber 24 and is adjustable. The stem 30 which actuates the lamp has a bore which conveys pressure-fluid from the chamber 23 to the conduit 31 according as the radial outlets of the bore are uncovered from the casing 21. Fig. 5 (not shown), illustrates a similar modification with a fourth diaphragm and an additional conduit to compensate for the effect of a filter in the main fuel conduit. It is stated that the diaphragms could be replaced by pistons.
